Abstract

114,615. Tua, G. Nov. 24, 1917, [Convention date]. Addition to 111,851. Switches, quick-action.-In the multiple-position turn switch described in the parent Specification, the lower fixed cam member 1 is made in one piece with the insulating base 2 and the movable member 6 fixed on the operating-spindle, is also made of insulating-material and has cam projections 5a normally engaging the recesses in the fixed cam member. The spring contact member 11 bears upon the side of the movable cam member which is formed with recesses 6b, Fig. 5, which, in the ' on ' position of the switch, receive a cam projections 11<a> on the contact member and enable it to engage with the fixed contact 4a. The quick movement is produced by a spiral spring which tends to keep the fixed and movable cam elements together, as in the switch described in the parent Specification. By the use of two contact members and two recesses in the sides of the movable cam member spaced apart at 90 or 180 degrees, the switch may be used as a two-way switch.
